YUASA/NSK BANTAM SERIES
The Bantam Series air motor spindles have been
designed for drilling and end-milling using small
diameter cutting tools.

8,000~16,000 RPM
POWER OUTPUT 132W
BANTAM 250
YUASA
15,000~26,000 RPM
POWER OUTPUT 105W
Bantam Characteristics:
High torque air motor spindle features less vibration which is excellent for small
diameter drilling and milling, and ensures an ultra-smooth finish when grinding inside
and outside of cylindrical surfaces.
The air driven system produces very little heat permitting long periods of continuous
smooth operation.
The spindle runout is a maximum of 8 microns for high accuracy.
The Bantam units feature ultra-precision angular contact bearings with a concentricity
of 8 microns providing the combination of high accuracy and strong rigidity.
Rotational speed can be regulated by varying the air pressure.
Muffler reduces noise level down to 60dB max.
Air consumption of 170 l/min. max. Energy saving mechanism allows use of small air
compressor down to 2.2kW (3 HP).
High torque allows the use of grinding tools for grinding bore, O.D. and sides.
Vane type air motor offers high output power for it's size and allows it to be used in
a wider range of applications that require high torque.

Application:
Small diameter milling and drilling using conventional vertical milling or machining centers can be a
problem if the maximum spindle speed is too
slow. Tool chattering and excessive heat build-up
can cause shorter life to the cutting tools and
produce rough working surfaces. The Bantam
high-torque air motor solves these problems
because the VMC's spindle does not rotate.
Simply install the Bantam into the main machine
spindle and supply the air.

ASTRO SYSTEM
YUASA
The Astro Series incorporates air motor spindles providing the
necessary speed and torque to accomplish a wide variety of
machining operations such as grinding, boring, drilling, chamfering
and deburring. Astro spindles can be mounted to any NC or
manual lathe to either the compound slide or tool post. By using
multiple Astro spindles, primary and secondary operations can be
performed in a single set-up. A simple chucker lathe can be
turned into a CNC turning center.
Five different air motors are available up to 60,000 RPM. A
variety of gear reducers can be inserted between the Astro air
motor and spindle enabling "low speed" and "high torque" for
various machining operations using many different materials.
The outer housing of the Astro spindles, gear reducers and air motors
is made of stainless steel, and when connected, create a solid single
unit.
Ultra-precision vane type air motors
provide high torque while maintaining
extremely quiet operation.
